Fix crashes when using the QImage(uchar *) data constructors
The constructors expect a range of memory that remains valid
through the lifetime of the image and may also modify it.
Crashes occurred since apparently the Py_Buffer was released before
it.
To fix this, add a new buffer helper, copyData() that makes a copy
of the data and pass that along with std::free() as cleanup
function.
Fixes: PYSIDE-1563
